BICYCLE TOOL-BAG.

SPECIFICATION forming' part Of Letters :Patent N0. 588,059, dated August 10, 1897.

Application iiled August l5, 1896. Serial No. 602,845. (No model.)

Be it known that I, DANIEL D. FROTIIING- HAM, of SalemJ in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Bicycle Tool-Bags, of which the following is a specification.

This invention has for its object to provide a strong and durable tool-bag for use on bicycles which shall present seamless or joint-' less angles at the intersection of its ends, sides, and bot-tom, and shall also present smoothsurfaced outer ends or heads and sides, free from project-ing angles or shoulders.

Theinvention consists in theimprovements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specication, Figure l represents a perspective view of my improved tool-bag. Fig. 2 represents a perspective sectional view showing a portion of the same, the section being on the plane of line 2 2 of Fig. l. represents a section on line 3 3 of Fig. l. Fig. 4 represents a plan of the blank from which the bag is made.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents the bottom o the bag, which is provided at its ends with V-shaped extensions a.

b b represent the sides of the bag, which are provided at their ends with extensions b b', the lower portions of which are inclined to t the inclined ends of the extensions d', as shown in Figs. l and 2.

c represents the cover of the bag, which is a continuation of one of the side pieces Z2 and has a flap c', adapted to bear on the other side piece of the box when the cover is closed.

The parts above mentioned are all made in one single integral piece of suitably thick and durable leather, the kind commonly known as .sole-leather being preferred.

d d represent rectangular end pieces o1' heads, two of the edges of each of which are formed to bear upon the inner surfaces of the sides b b, another edge of each bearing on the bottom u. Said end pieces or heads give'stability and stidness to the ends of the bag, acting as braces to prevent the sides and bot- Fig. 3'

tom from being bent or forced inwardly at the ends of the bag. The extensions a b b are bent over the bottom and side supporting edges of the heads d, their inner surfaces bearing against the outer sides of said heads. The edges of the extensions a' o' b are formed to abut against each other along their entire length, as indicated in Fig. l, the inclined portions of the edges of the extensions b f1tting the inclined edges of the extension d', so that when the said extensions are in place on the outer surfaces of the heads d they collectively constitute smooth-surfaced outer ends or heads which are free from projecting angles or shoulders. The extensions are secured to the end pieces or heads d d along their edges by suitable metallic fastenin gs f, which are preferably small wire staples driven through the extensions and end pieces and clenched upon the inner surfaces of the end pieces d, as shown in Figs. l and 3.

It will be seen that the extensions d b' b', which are integral with the bottom and sides of the bag and are bent over the end pieces or heads d d, constitute seamless or jointless corners at the intersection of the sides, botf torn, and ends of the box. Consequently there are no raw edges or seams, the outer or grain surface of the leather extending continuously without interruption over the said corners. The bag is thus given a smooth exterior, and being free from projections or angles it is less liable to be torn by contact with external objects than would otherwise be the case.

It will be seen that the end pieces or heads d d by supportingtthe sides and bottom of the bag, as above stated, prevent any independent Inovement of the extensions ct b' b', and therefore prevent the wearing of said extensions `on the metallic fastenings, which would be liable to occur if said extensions were simply overlapped and secured together without the end pieces or heads d d bearing against the sides and bottom of the bag.

I claim- A bicycle tool-bag, comprising a bottom a, V-shaped extensionsd d' at the ends of the bottom, sides b b, extensions b' b at the ends of said sides, a cover c forming an extension of one of said sides, all being made in one single integral piece, and separate end pieces loo o1' heads d cl having edges bearing on the innersurfaees of .the bottom and sides, and sides bearing on the inner surfaces of the eXtensions a and b', the said extensions being bent p over the side and bottom supporting edges of the end pieces to form seamless or jointless corners, and riveted to the end pieeesol heads along their edges, said edges being formed to abut against each other and form smooth-survfaced outer heads or ends Which are free from projeetin g angles o1 shoulders, the entire ex- DANIEL D.
